Democracy Corps' website is on the fritz for now, so I can't link to any crosstabs right away. We'll get you the straight dope once it's available, though.
Rasmussen Reports (9/9, likely voters, 8/25 in parens):
Jon Corzine (D-inc): 38 (42)
Chris Christie (R): 46 (50)
Chris Daggett (I): 6 (-)
Undecided: 10 (7)
(MoE: ±4.5%)
This is the first time that Rasmussen has actually included independent Chris Daggett in the mix, and he clocks in at a not-insignificant 6%. Rasmussen also cheekily threw in a few "Who do you trust more?" questions on taxes, "cutting" government spending, and corruption, and -- surprise, surprise -- found Christie in the lead in each column. Of course, no questions were asked on issues that may have played to Corzine's strengths, but, hey, this is Rasmussen.
